All three files contain the same code. Download the most convenient one.

Downloading Notes: 

VBS FILE
IE may try to run the VBS file instead of downloading it! You'll 
have to right-click and select "Save Link" or "Save Target" to save 
the file to your hard drive. 

TXT FILE
Be sure to save the downloaded file with a VBS file extension. If your 
Windows has the default behavior of hiding file extensions, you will 
have to quote the file name. For example, don't save it as test.vbs, 
but as "test.vbs". Using quotes forces Windows to honor your file 
extension.

ZIP FILE
No problems. The zip file may (or may not) contain other information 
or directions.

Creates an MP3 from plain text. 

If a TXT file is dropped on the script, an MP3 file will 
be created with the same base name and in the same folder.
If a folder is dropped on the script, any text in the 
Windows clipboard will be made into an MP3 in that folder.
If a JPG file was dropped on the script in the previous 5 
minutes, it will be used as cover art only once.
If no JPG file was dropped on the script, the most recent JPG 
picture (if any) in the destination folder will be used as 
cover art for any MP3 created in that folder.
If this script is run from an administrative command prompt, 
it will toggle right-click options for folders, TXT, and JPG.

The voice used (e.g., "Microsoft Anna") is specified in a CFG 
file named "StoryReader.cfg" (for compatibility with other 
scripts). That file contains two lines like...
object=Sapi.SpVoice
voice=0
...where the voice is the index to one of your installed voices.
If the CFG file doesn't exist, we'll use the first voice we find.
Although you can manually create the CFG file, it can be created 
for you by running "VoiceChooser.hta" from:

As written, this script might create two additional programs:
  #  In order to create an MP3, a command-line MP3 encoder is 
  needed. If "ffmpeg.exe" and "lame.exe" are not available 
  in the path, then "lame.exe" will be created in the script's
  folder (ffmepg is better, but lame is smaller).
     Get "lame.exe" from http://lame.sourceforge.net/
     Get "ffmpeg.exe" from https://ffmpeg.org/
  #  In order to read the Windows clipboard, we will try to
  use 32-bit "AutoItX3" if it's installed on the system. If 
  it isn't, we'll try to install 32-bit AutoItX. However, 
  AutoItX can only be installed as an administrator, and since 
  nobody runs as administrator (right?), then we'll fall back 
  to using Internet Explorer. The trouble with IE is that the 
  clipboard feature could be removed. It's also annoying because 
  it asks if you want to allow access to the clipboard every time.
     Get the AutoItX version 3 DLL from: 
     https://www.autoitscript.com/site/autoit/downloads/
     Get the AutoItX version 1.51 DLL from:
